Abstract
A measuring device is described which has a metal body deformable in accordance with a value to be measured. A sensor element having a metal carrier and ohmic resistors formed thereon in metal thin-film technique is connected to the metal body by welding and generates a signal adapted to be electrically evaluated which corresponds to the deformation of the metal body. The weld for connecting the metal body and the sensor element completely encloses the metal carrier at its circumference. The metal body has, at the welded connection with the metal carrier, a material thickness t which is completely penetrated by the weld. The value to be measured by the measuring device comprises force, pressure, temperature, torque or combinations thereof.
